2. Imagine a net fishery for a medium sized fish like flounder that takes a large amount of unintended catch in the form of small crustaceans and fish that must be thrown back into the sea (usually dead). You are the fishery scientist who set catch limits for this particular fishery. You did your research and believe that the limits you set are sustainable, but the fisherman tell you they are catching smaller and fewer fish. What would you tell them you think the most likely problem and is and how to address it?
a. The problem is likely global warming, and the only way to solve it will be to address global warming.
b. The problem is likely that your research is outdated and you need to collect new data, set and establish new limits.
c. The problem is likely the increasing level of decaying shrimp and small fish in the area, and could be addressed if the fisherman found a new way to dispose of the unintended catch.
d. The problem is likely the large amount of bycatch is reducing food availability for the flounder, and could be addressed by designing new nets.
3. What application of biotechnology seeks to make a positive impact on human health by searching the marine environment for novel compounds, such as new drugs?

Which of the following is an example of aerobic respiration? A.Lactic acid fermentation in human muscles B.Physical exchange of gases in human lungs C.Respiration during vigorous physical exercise D.Breaking down of glucose with oxygen inside an animal cell
D. Breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.
Lactic acid fermentation occurs in human muscles and it is not a type of aerobic respiration as it occurs in the absence of oxygen gas. In this process, lactate or lactic acid is produced by the glucose. Physical exchange of gases in human lungs is called breathing. Respiration during vigorous physical exercise is an example of anaerobic respiration because vigorous physical exercise creates deficiency of oxygen. Aerobic respiration is a type of cellular respiration in which the glucose is broken down to release energy in the form of ATP or adenosine triphosphate in the presence of oxygen. This type of respiration occurs in both animal and plant cells. Hence, breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.Learn more about aerobic respiration:

What effect will the settling of sediment have on the shape of the stream?
The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
Answer:
Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?
Answer:
The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

A terrarium is a small, enclosed ecosystem. If you change certain aspects of the terrarium, the climate that exists inside it will also change. Examine the image of a terrarium. Then identify one attribute of the terrarium that you could change to alter the climate inside. How would this change mimic the climate changes that we see on Earth?
Answer: Putting a lid on the terrarium will increase the humidity.
Explanation:
Putting a lid on the terrarium will increase the humidity.
What is Humidity?Humidity is a measurement of the air's water vapor content. If there is a lot of water vapor in the air, the humidity will be high. As the humidity increases, it feels more humid outside.
In weather reports, humidity is frequently described using the word "relative humidity." The percentage of the maximum quantity of water vapor that the air can hold at a given temperature that is actually present in the air is referred to as relative humidity.
A chilling -10 degrees Celsius in the air (14 degrees Fahrenheit). At this temperature, the air can only hold 2.2 grams of water per cubic meter.
Therefore, Putting a lid on the terrarium will increase the humidity.

CH3OH + HOCH3 = CH3-O-CH3 + HOH Is this reaction an addition reaction or a dehydration reaction or synthesis or whatever? A. Addition B. Dehydration Brainliest for the correct answer. Pls help
Answer:
B. Dehydration
Explanation:
Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.
Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.
For example: RCO2H + R′OH ⇌ RCO2R′ + H2O
In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH
The reaction is showing dehydration because two molcules are combined aand water molecule is eliminated from the reactant.
Hence, the correct option is B. Dehydration.
In recent years, scientists have collected data on the extent of sea ice in the Arctic Ocean as shown in the graph. What additional data could be used to support or refute the theory of global climate change?

O A graph providing data on average global temperatures from 1980 to 2010
O A graph showing monthly fluctuations in sea ice extent for each year 1980 to 2010
O A graph showing yearly fluctuations in sea ice extent for each year 1980 to 2010
Answer:
Option 2, or B
Explanation:
The most practical data would be global temperatures during the 37+ year time period to coincide with the thinning sea ice. Option #1 is far too broad to include (daily), as is option #3 (monthly). The last option is basically proposing to duplicate what the graph already shows.
The additional data that could be used to support or refute the theory of global climate change is as follows:
A graph providing data on average global temperatures from 1980 to 2010.Thus, the correct option is B.
What is Climate change?Climate change may be defined as the long-term shifting or alteration in the average temperatures and weather patterns.
The graph given below illustrates the average temperature from 1980-2010. It is not possible to represent the daily or monthly average temperature of approximately 30 years.
